13 Claims. (Cl. 11-1) This invention relates to improvements in devices for applying adhesive to corresponding'edges of sheets of paper or the like to form sets of two or more sheets. The device is primarily intended to'be an attachment coordinated with or otherwise connected to another sheet material handling machine, as, for example, a printing press or paper collator. Although attachment of my device to a printing press is principally referred to in this application, since the printing press illustrates and develops the use and capacity of the invention, it must be clearly understood that my attachment may be used with many other types of machines and combinations of machines, or as a part of a self-contained unit.

The present invention in general is concerned with improvements for certain purposes over the inventions disclosed in my co-pending application, Serial No. 657,- 407, filed May 6, 1957, now Patent No. 2,925,611, and constitutes a continuation-in-part of my said co-pending application.

An object of this invention is to provide a pasting .machine for use with a printing press or any other machine which delivers sheets of paper to a delivery station, for applying adhesive to corresponding edges of a selected number of sheets in coordination with the delivery of sheets to the delivery station.

Another object of this invention is to provide an automatic pasting machine of the type referred 'to which in each set of sheets, and the means of adjustment for is efiicient and'whicheliminates the need for hand labor in pasting the edges of the sheets of paper or the like together.

A further object is to provide a pasting machine of the kind mentioned which may be attached directly to the delivery arms of the printing press, thereby operating in unison and synchronism with the 'press without interfering with the normal operations of the press.

An additional object of this invention is to provide a pasting machine of the kind referred to which continuously applies adhesive to corresponding edges of sheets of paper or the like to form sets of sheets oftwo sheets or more as may be predetermined, leavingeach set "separate from the other. 7

Another object of this invention is to provide a pasting machine of the type mentioned which is capable of applying adhesive to a selected number of sheets, then omitting adhesive from a sheet, and then continuing in a similar manner with the application of adhesive to another set of the selected number of sheets, followed by the omission of adhesive from a sheet, ad infinitum.

A further object of this invention is to provide a'pasting machine as mentioned which comprises a compact single unit which may be easily and quickly attached to or removed from a printing press or similar "machine.

The machine may'be swung aside when desired without of the type referred to wherein the means of adjustment "for-predeterminingthe number of sheets to becontained increasing the amount. of adhesive to each sheet are sim-.

ple and convenient to operate.

Other objects and advantages will be apparent from the following description and drawings.

Fig. 19 is a side elevational view showing a cam which press deposit sheets of printed matter on table 35 in the delivery station of the press. Thedelivery arms 33 and 34-of the press are actuated in oscillatory manner in the conventional manner. As hereinafter shown the power requirements of my pasting machine are derived from the oscillation of the delivery arms 33 and 34, but does not interfere with the normal operations of the press.

My improved pasting machine is a compact single unit which is easily attached to a printing press or other machines. The drawings illustrate the attachment of my machine to press guards 31 and 32 respectively by outer legs 36 and 36a of L-shaped mounting brackets 37 and 38 with nuts and bolts or other means as at 39. The inner leg 40 of left L-shaped mounting bracket 37 is secured to mounting 41 within groove 42 by bolts or other means as at 43. Mounting bracket 40 carries elongated holes 44 for ready fitting to presses of varying size. Mounting 41 carries pin 45 the upper portion of which is unthreaded and the lower portion of which is threaded through mounting 41 with lock nuts 46 for ready vertical adjustment of my improvement on the press.

The inner leg 47 of right L-shaped mounting bracket 38 is secured to mounting 48 with groove 49 by bolts or other means as at 50. Mounting bracket 38 carries elongated holes 51 for ready fitting. Mounting 48 carries threaded pin 52 which is threadedthrough mounting 48 with lock nuts 53 for ready vertical adjustment of my improvement. Threaded pin 52 carries hand nut 54 with collar 55.

Frame member 56, which carries my attachment, has bored block 57 secured at one end with a bore 58 of sufficient size to accommodate pin 45. At the other end the extension 59 of frame member 56 carries a slot- 60. In order to mount my device at the delivery end of the printing press mounting brackets 37 and 38 are respectively attached to printing press guards 31 and 32. The bore 58 of block 57 pivotally fits over pin 45. Frame member 56 is swung on pin 45 until it extends transversely across the delivery end of the press, with pin 52 fitting within slot 60. Hand nut 54 and collar 55 are turned on pin 52 to retain frame member 56 securely in position.

Frame member 56 has a recessed area 61 within which is seated a trough for adhesive reservoir 62 containing an adhesive. I have found that saturation of a sponge 63 which fits within the adhesive reservoir 62 with an appropriate adhesive is very satisfactory. Paper stop 64 is secured to frame member 56 by screws 66 forward of adhesive reservoir 62. Substantially parallel upward- 1y extending fingers 65 extend from the base of the paper stop 64, and the sheets of paper 67 delivered from the press are brought to rest against the fingers 65.

The adhesive applicator generally referred to as A consists of a plurality of arms 68 which are pivotally secured to carrier bar 69, and substantially prevented from horizontal movement by snug fitting rubber washers 70. Carrier bar 69 is secured at one end to crank 71 which is pivotally connected to bracket 72 which extends upward from frame member 56. The other end of carrier bar 69 is secured to crank 73 which is fixedly secured to gear wheel 74. Gear wheel 74 is pivotally secured to bracket 75 which extends upwardly from frame member 56. The tail portions 76 of arms 68 unattachedly rest upon applicator rest 78 which is rigidly secured to brackets 79 and 80 which extend upwardly from frame member 56. Each of the forward ends of arms 68 has a downturned finger 81 which is dipped into the adhesive which adhesive is then deposited on the edge of sheet 67 as the arms 68 oscillate forward and backward as hereinafter described.

Means for operation of the adhesive applicator, and the means for interrupting the application of the adhesive to selected sheets of paper in order to make set of sheets, are connected to and coordinated with the movement of the delivery arms 33 and 34 of the printing press. The means for oscillating the adhesive applicator arms 68 backward and forward consists of gear wheel 82 which -is pivotally secured to bracket 80 by bushing 83, and

; matically interrupts the normal applicator stroke, re-

straining the adhesive applicator from coming in contact with the top sheet of paper 67 at regular intervals.

This interruption of the applicator stroke permits the sheets to be glued together in sets of a'predetermined number of sheets, such as 2, 3, 4, etc., sheets" to a set.

Thus, sheets of the same kind may be delivered, as where attached to a printing press only. Upon attachment to a printing press and carbon paper feeder or interleaver my device will automatically provide sets of printed sheets with carbon paper interleaved between them, with the sheets and carbon paper merely glued at one edge thereof for easy separation.

Shaft 89 is rotatably mounted through supporting brackets 90 and 91 and bearings 92 and 93 which are secured to frame member 56. Collars 94 and 95 with set screws 96 prevent horizontal movements of the shaft 89 within brackets 90 and 91. Ratchet wheel 97 is rigidly secured to shaft 89, and is revolvingly carried within outer wheel 98 which has notch 99 in its periphery. Outer wheel 98 carries well-known clutch device 100 with members 10011 which grasp and turn shaft 89 when turned in one direction, but releases shaft 89 when turned in the other direction, similar to the usual ratchet action. Thus, ratchet wheel 97 is caused to turn when the outer Wheel 98 is turned in one direction, but releases the ratchet wheel 97 when the outer wheel is turned in the other direction. A conventional ratchet 97a and pawl 101 arrangement may be used in like manner as shown in Fig. 20, where pawl 101 is pivotally secured within ratchet wheel 97 and engages notched ratchet 97a as to turn shaft 89 when turned in one direction, but without turning it in the other direction. Spring 102, which extends from frame member 56 to pin 103 on outer wheel 98, causes outer wheel 98 to return to the position shown in Figs. 2- and 6.

Reciprocating arm 104 is pivotally secured by bolt 105 to the opposed side of outer wheel 98. Outer wheel 98 also carries pin 106 which limits the backward movement of reciprocating arm 104. Reciprocating arm 104 carries crank 107 which is in reciprocating engagement with delivery arm 33 of the printing press. 9

Support member 108 is secured to frame member 56 and has a bore 109 (dotted lines in Fig. 6), through which rotatable pin 110 is extended. Knob 111 is secured to the outer end of pin 110 and cam 112 is secured to the other end of pin 110. Knob 111 may be marked with letters A, B, C, etc., or other appropriate markings to correspond with the various surfaces A, B, C, etc., of cam 112.

Cams 113, 114, 115, 116, 117 and 118 are carried near the opposed end of shaft 89, and are horizontally slidable as a group on the shaft. Cams 113-118, inclusive, are moved back and forth on shaft 89 as may be necessary to provide for the desired number of sheets of paper in each set of sheets. These cams are moved on shaft 89 by pin 119 which extends downward from adjustment bar 120. Adjustment bar 120 is pivotally secured to frame member 56 at 121. The other end 122 of adjustment bar 120 extends over edge portion 123 of frame member 56, with holes 124 of adjustment 'bar 120 in communication with the respective holes 125-130 of frame member 56 as the end 122 of adjustment bar 120 1s drawn along edge portion 123 of frame member 56 on pivot 121. Lock pin 131 may be placed through holes 124 of adjustment bar 120 and one of the holes 125-130 on frame member 56 to retain the cams 113118 in such stationary horizontal position as maybe desired.

L-shaped stop control member 132 ispiv'ot'ally'secured to support member 133 extending from frame member 56 and at one end carries wheel cam follower 134 and has lever 135 adjacent said end. The other end of stop control member 132 is pivotally connected to stop member 136. Spring 137 connected near the latter end of the stop control member extends to support member 138 at 137a so as to retain tension of wheel cam follower 134 against the respective cams 113-118. Stop member 136 is in slidable communication with aperture 139 of support member 138.

The programming part P of invention secured beneath frame member 56 may be enclosed by box 140 with appropriate apertures 141 to accommodate outward extending lever 135 and knob 111.

Operation In operation my machine is attached to the printing press at the delivery end adjacent to table 35 in the manner above-described. It does not interfere in any way with the normal operation of the printing press. Push rod 87 'is easily engaged with or disengaged from delivery arm 34 by removing crank 88from the hole in the delivery arm, and reciprocating arm 104 is likewise easily engaged with or disengaged from connection with delivery arm 33 by bolt 105. My attachment will apply adhesive to the edges of sheets in sets of two or more sheets, without an application of adhesive to the top sheet of each set. By simple adjustment hereinafter described my machine is capable of automatically 'prow'ding sets of two or more sheets, as desired, depending upon the particular job order, so that sets of two sheets, or three sheets, or four sheets, or more, may be provided.

As the printing press delivers freshly printed sheets to table 35 of the printing press delivery station, they move to fingers 65 of paper stop 64 and are brought to rest on table 35. As each sheet is so delivered my machine is set in motion, being motivated by and in coordination with delivery arms 33 and 34 which move in unison. As the delivery arm 34 moves to the position in relation to lever 84 and push rod 87 shown in Fig. 3, the applicator arms 68 are moved in unison to the adhesive-obtaining position with applicator fingers 81 in contact with the adhesive in adhesive reservoir 62. This is accompanied by a simultaneous movement of applicator arms 68 which are pivotally secured to carrier bar 69, the tail portions of said applicator arms resting on applicator rest 78. The depth to which the applicator fingers 81 are extended into applicator reservoir 62 may be adjusted by adjusting the length of the stroke of lever 84, collar 86 and push rod 87. Such adjustment may be made by loosening bolt 85a and sliding collar 86 within crank 85 to the desired position, and then tightening bolt 85a to maintain the desired length of stroke.

As delivery arms 33 and 34 move further in their single cycle of operation and in a direction to obtain another sheet for the delivery station, the applicator arms 63 are oscillated from the position shown in Fig. 3 t the position shown in Fig. 4 as gear wheel 74 is turned as a result of the movement of delivery arm 34. As

shown in Fig. 4 the applicator fingers 81 in unison gently touch the top sheet 67 and apply adhesive thereto to cause the set of sheets to stick together. Then, as delivery arms 33 and 34 are ready for another stroke the applicator arms 68 and fingers 81 are returned toward the position shown in Fig. 3.

Simultaneously with the above-described movement of the applicator means A the oscillation of reciprocating arm 104 through its contact with delivery arm 33 sets in motion the means for interrupting the application of adhesive tat fixed intervals in order to provide sets of the sheets with a specified number of sheets. The movement of reciprocating arm 104 causes outer wheel 98 to turn a part of a revolution. As members 100a grip shaft 89 (or as pawl 101 engages ratchet 97a) shaft 89 is causes outer wheel '98 :to return to its original position with the ratchet action therein in disengaged relation; so that shaft 89 does not turn when wheel 98 returnsto such original position. The distance that outer wheel 98 andshaft 89 rotate is adjusted by the turningof knob 111 to the positionA, B; or C, which in turn determines whether surface A,.B"or Cof cam v112 will rest against the shoulder 99a of notch 99 of the outer wheel 98. It will be noted thateach'of the surfaces A, B, and C of earn 112 has a different distance from the center-Of pin 110, and therebythe distance 'of rotation of wheel 98 and shaft 89 will vary depending upon theadjustment of knob 111. l

The number of sheets-in each *set is then determined by the respective cams 113'118,in relation tothe distance that shaft '89 is turned and in cooperation with wheel cam follower 134. To illustrate, if sets of three sheets are to be produced the cams are positioned by moving end 122 of adjustment bar to the hole 126 which-carries the number 3 until wheel cam follower 134 is in communication with cam 117, and knob 111 is turned so as to have surface A ofcam 112 against the shoulder 99a of outer wheel 98. When wheel cam follower 134 travels in each of notched surfaces 117a the cycle of the adhesive applicator A is complete from adhesive reservoir to the application of the adhesive to the edge of top paper 67. However, when cam 117 revolves sufliciently so that wheel cam follower 134 travels in the deeper notch 1171) of earn 117 as a result of the tension of spring 137,- stop member 136 is caused to extend outwardly from support member 138 in the path of lever 84. Thus, lever 84 is prevented from making a full swing by the projecv tion of stop member .136 and applicator fingers 81 are restrained from contacting sheet 67 as shown in vFig. 5. In such case the movement of delivery arm 34 is absorbed by the spring (not shown) within collar 861 Hence, adhesive is applied :to two successive sheets -delivered to table 35 and-no adhesive is delivered to .the third or top sheet, so that a set of :three sheets is produced. a

Likewise, if a set of seven sheets is desired knob 111 is turned so that surface C of earn 112 :is in contact with shoulder 99a of outer wheel 98. Adjustment bar-end 122 is moved to the number 7 hole on edge portion 1'23, and wheel cam follower 134 is in communication with cam 113. With such adjustment adhesive is applied to six successive sheets by applicator fingers 8'1, and no adhesive is applied to theseventh or top sheet of the set. It is obvious that with variations in cam 112 :and cams such as those at 113 to 118, sets containing almost'any number of sheets may'be .produced, as desired.

It is to be understood that the present invention is not confined to the particular constructiorn'and arrangement of parts herein illustrated, but embraces all such modifications andalterations thereof, as may come within the scope of the following claims.
